[−][src]Struct tide::Before
Define a middleware that operates on incoming requests.
This middleware is useful because it is not possible in Rust yet to use closures to define inline middleware.
Examples
use tide::{Before, Request}; use std::time::Instant; let mut app = tide::new(); app.middleware(Before(|mut request: Request<()>| async move { request.set_ext(Instant::now()); request }));
